"If we look at certain proteins, yes, man then -- it can be assumed that man is more closely related to a chimpanzee than other things. But on the other hand, if you look at other certain proteins, you'll find that man is more closely related to a bullfrog than he is a chimpanzee. If you focus your attention on other proteins, you'll find that man is more closely related to a chicken than he is to a chimpanzee."
